Letters Patent No. 112,177, dated February 28, 1871.

' IMPROVEMENT IN PUMPS.

The Schedule refened to in these Letters Patent and making part of the same.

To all whom 'it may. concern:

Be. it known that I, JOHN S, Punto, of the city of Rochester, in the State of New York,V have invented a` new and useful Pump; and Ido hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawing making part of this 'speeiiication,.in which- Figure 1 is a vertical section.

Figure 2 is a top view of the curbing of the well, showing the position of braces forming thefulcrum of the levers. v o

Figure 3 is a front elevation of part of the induction-pipe, and the connecting-rods and cross-bar, to which theplunger-rod is attached.

This invention will be understood from the drawing and specification.

ATo enable others skilled in the art to make and use my inventioml will describe its consti-notion and operation.

On the bottom of the eduction-pipe A of a pump I attach a metal water-chamber, B, closed at both ends, and made in two parts, fastened together by means of bolts put through flanges on the edge of each. v

In the bottom of the chamber an induction-port, a, is made, which is provided with a valve, c.

Inside of the eduction-pipe A I place a tube, d, of India rubber or other suitable material, which extends from the discharge-pipe G down to anyrequred point below the line of frost, and is made less than the diameter of the boreI of the pipe A, which is enlarged in this section.

braces F, which form the fulcrurn of the compound` levers H( y l. I then pass down through the pipe A a rod f, which extends down into the chamber B, on the bottom of which is fastened a plunger, B.

This plunger is .formed by making a metal ring, A', smaller in diameter thanthe chamber to admit a packing-the inside being made a cone-shape about half through, as shown at lv, in iig l.

On the top I it a cover, x, in which two or more eduction-ports are made, which have valves y to prevent the water flowing back when the rod is moving upward; these valves are held in their places by the rod f on the bottom of the cone-'shaped part B'.

A cover, ci, is also provided, through which there are holes to allow the water to pass.

' The packing fi of the plunger B' is similar to that in packing is then placed between the two parts of the` chamber B and are held iirmly between their langes.

The top of the rod f is passed through the crossbar G, which is sustained by posts o bolted to the-short end of the compound lever H, over the well It, so that as the lever moves it causes the rod f and its attachments to work vertically.

The braces F are placed so that they rest ou the side of the top of the curbing of the well h.,'and may extend into the stone work on the opposite side, as shown iuhgs. -1 and 2, or may butt up against it.

The compound lever H consists of the single levers J and K, one of which, J, is pivoted to the braces F and extends back in the rear of the eduction-pipe A,

and has a platform on which a counterbalance, P, is

placed. To the other end of, J the other single lever K is pivoted by aconnecting-rod, y', which may .be shifted inand out to alter the power applied to the pump without altering the balance-weightj; and the lever K is also pivoted at the other cud to a bearing, R, suitably fastened in a platform or in the ground.

Ou the single lever J a trough, S, is placed, having a hole, c3, so that after the animal has left the platform .of the lever K, and the lever J rises np, any water left will ow out, as the trough S is raised, at the side .opposite the hole c3.

The object of this invention is to make a pump by which the animal may draw the'wa-ter required, and I find that this'method of arranging the levers is preferable to the one set forth in my patent V0i' June 5, 1866.

-Its operation is' as follows:

The animal going on the platform I?2 on the levers K of the comgzlnlund lever H, depresses both parts of it and raises up t e rod f, and the plunger B attached, which causes suflicient water to flow up tlir'ough the pipe A, and, at the same time, drawing water from the well and lls the portion of the chamber B below the plunger.

After the animal leaves the4 platform the ,counterbalance P cusesV the levers to raise :md-depress the levers causes it to ow up the pipe A.

The'rubber tube `is placed in the pipe A so that if the water should freeze the movement of Vthe rod will displace it, as ice will not adhere to rubber, and being smaller than the bore o f the pipe A the water willY cause it to expand and' pass up by the side of the ice sind melt itv away.

The ring b, in addition to the pressing out the rubber tube, as set forth, serves to contract the bore of the eduction-pipeA at that point, and prevents the water from flowing out with a. sudden gnsh and producing a. noise that frequently Afrightens the animal'.

Ypurp0ses1set forth.
